Mesoscale Discussion 2023 NWS Storm Prediction Center Norman OK 0939 PM CDT Tue Aug 27 2024 Areas affected...Parts of northern IL into extreme northwest IN Concerning...Severe Thunderstorm Watch 658... Valid 280239Z - 280415Z The severe weather threat for Severe Thunderstorm Watch 658 continues. SUMMARY...Some threat for hail and damaging wind may persist through late evening. DISCUSSION...Convection has largely become outflow dominant this evening across northern IL, within an environment that is strongly unstable (with MLCAPE of 3000-4000 J/kg), but with only weak to marginal deep-layer shear. Favorable thermodynamic profiles (as noted on the 00Z ILX/DVN soundings) will continue to support briefly intense updrafts with isolated hail potential. A large area of convective outflow has moved into western IL from northeast MO/southeast IA, with smaller outflows being generated by redeveloping storms within the primary instability axis. Locally damaging winds may accompany this outflow-dominant convection through late evening, before increasingly extensive convective overturning results in a weakening trend overnight. ..Dean.. 08/28/2024 ...Please see www.spc.noaa.gov for graphic product...
